Abstract

Cette invention a trait au bruit produit pendant le fonctionnement et qui est réduit par la réduction de l'occurrence du son de l'écoulement du fluide frigorigène. Un appareil frigorifique (1) utilise un fluide frigorigène supercritique et fonctionne dans la plage d'une pression élevée supérieure à la pression critique. L'appareil frigorifique (1) comprend un compresseur (21), des refroidisseurs de gaz (23, 31), des mécanismes de détente (V2, V5), des évaporateurs (31, 23), des moyens de détection de pression de décharge (T1, T2, T3) et une section de commande (5). Le compresseur comprime le fluide frigorigène supercritique. Les refroidisseurs de gaz refroidissent le fluide frigorigène supercritique comprimé par le compresseur. Les mécanismes de détente réduisent la pression du fluide frigorigène supercritique. Les évaporateurs évaporent le fluide frigorigène supercritique dont la pression a été réduite par les mécanismes de détente. Les moyens de détection de pression de décharge détectent la pression de décharge du compresseur. La section de commande effectue une commande pour ajuster les ouvertures des mécanismes de détente de telle sorte que la pression de décharge peut être supérieure à la pression supercritique lorsque la pression de décharge est inférieure à la pression supercritique lorsque le réfrigérateur est démarré.
